If you love citrus desserts like these Keto Lemon Bars and Glazed Lemon Poppyseed Bundt Cake, you will LOVE this Dairy-Free & Keto Key Lime Pie!
It's easy to make, extra creamy, and has a graham cracker style crust with the perfect sweet/tart ratio!
Key limes are a bit smaller and pack more of a punch than regular limes and are the star ingredient. However, key limes can be harder to find so this recipe will work with any limes you can find!
The keto sweetener
For the crust, I use an erythritol-based keto powdered sweetener. I use an erythritol-based sweetener because otherwise, the crust will turn out too soft.
For the filling, any keto powdered sweetener should work. I always use Powdered Monk Fruit Erythritol Blend since that's what I use for the crust.
Also, if you choose Powdered Allulose, it’s only 70% as sweet as sugar. So if using allulose you’ll need to add a few extra tablespoons.
For Paleo, you can powder some coconut palm sugar. Just make sure the blender is completely dry! It will slightly affect the color and give it a slight caramel taste but will work.

How to make dairy-free key lime pie
To make a dairy-free key lime pie, simply sub the condensed milk with coconut cream!
For the coconut cream, place a can of full-fat canned coconut milk in the fridge for 24 hours then scoop out the coagulated cream.
I only recommend Thai Kitchen, Sprouts, and Native Forest brands because other brands may not separate well or have a funny aftertaste.
If the cream is too hard to stir, heat just a few seconds in the microwave or on low on the stove just until softened but not melted.
The crust
Preheat oven to 350 degrees.
Then, whisk together some almond flour, cinnamon, powdered sweetener, and salt in a large bowl and some melted butter (can use non-dairy or ghee).
Stir the melted butter and an egg into the dry ingredients and press into a lightly greased pie pan.
The mixture will be crumbly, however, if it's too crumbly to stick together, add more butter as needed.
Bake around 8 minutes, or just until starting to brown.
The filling
Whisk together freshly squeezed lime juice, lime zest, powdered sweetener, and coconut cream - starting with the lowest amount of lime juice and sweetener. Limes can vary a lot in taste, so taste the filling and add more lime juice and sweetener as needed.
Once you have the tartness and sweetener how you like, whisk in the coconut flour, eggs, and egg yolk then mix well.
As soon as the crust comes out of the oven, pour in the filling. By adding the filling to the hot crust, it keeps the filling from seeping into it.
Bake at 350 degrees for 20 to 25 minutes, or until the center is set. Allow to cool to room temperature, then place in the refrigerator to finish setting up. This will take approximately an hour.
Serve with Dairy-Free Coconut Whipped Cream and Enjoy!!
💭 Top tips
- Start with the lower amounts of sweetener and lime juice then taste the pie and add more as needed. Lime juice can vary a lot in taste, so tasting and adding more as you go will ensure the perfect sweet/tart ratio every time.
- Be sure to whisk the eggs and egg yolk into the batter really well. This will ensure the pie cooks evenly.
- To keep the filling from seeping into the crust: 1) Don’t poke holes in the crust when pre-baking and 2) Pour the filling into the crust and bake as soon as the crust comes out of the oven. If the crust puffs up while pre-baking, gently press it down before pouring in the filling.
- Please, please USE FRESH LIMES and not the reconstituted stuff, it's just not the same!

I love this recipe! I honestly had "diet food" expectations, but when I took the first bite, it was instantly one of my favorite desserts. My husband also loves it, which is saying a LOT because he normally doesn't like anything citrus based!
Oh, YAY Kay!!!
I'm so happy you and your husband liked it so much! Thank you so much for taking the time to let me know 😍

Hey Cassidy, it’s been a while sense I used this recipe. I thought it used agave for the sweetener instead of a powder. Did you change that’s? If so can you remind me of how much agave I would use?
Sadly, when I posted my Keto Key Lime Pie version I accidentally deleted the original version. Luckily, I had shared a few of my original recipes on Tasty Kitchen! Here is the link to my original recipe that uses honey or agave: https://tastykitchen.com/recipes/special-dietary-needs/dairy-free/dairy-free-key-lime-pie/
Enjoy your key lime pie!

Perfect recipe! I am a Chef who offers a Meal Delivery Service. I found this recipe and loved it! Came out perfect, was the perfect amount of lime flavor and not too sweet!

Hi I just pulled this out of the oven at 25 minutes and it’s a soupy mess I did not set up at all is it going to somewhat set up after I chill it? Or should it have already done something by now
I had the same problem! Ive made several key lime pies in the past but with evaporated milk, non coconut creme. I wonder if that is why its not setting up? Too much oil?
Amy & Erica,
I'm SO very sorry this recipe didn't work for you!!!
I've made this recipe many times and it's always turned out, but after your reviews I decided to test the recipe again. I tested it several times and it seems that not every time, but occassionally, it doesn't quite set up. And I definitley don't want a recipe that only has a 80% success rate - it needs to be 100!!!
To ensure that it NEVER happens I slightly adjusted the recipe. Again, I'm SO VERY sorry this didn't work for you. However, I hope you will try it again! Thank you very much for your feedback.

I can't believe this key lime pie is keto! Incredible!
Thanks for the awesome recipe ! Just made it, and the only think I changed was I added a little more sugar, because the filling was a little too tart, but that's just a matter of preference. Also was wondering if you used lime zest from the key limes. or did you use zest from regular limes ? I've never used key limes before, and was thinking that maybe their zest is more potent than regular limes are. I'll try cutting back on the lime zest next time. We're so excited to have this recipe, and it will be used often !
YAY Debbie, I'm so happy liked it!!! Yes, I did use regular limes so if you used key limes that's probably why yours was so tart - sorry bout that! I'll make a note in the recipe saying I used regular limes 🙂
I made this for my family for Easter and it was fabulous! No one else there other than myself has problems with wheat and dairy, but everyone loved it. Well, they would have preferred a normal crust, but they all could not believe that the pie was dairy and sugar free. YUM! Highly recommended!
YAY! I'm so happy you and your family liked it!!!! Thanks so much for coming back and letting me know 🙂
withoutadornment- You can definitely taste the lime but I didn't think it was too strong or overwhelming. If you prefer just a hint of lime you can always reduce the lime juice by 1 or 2 tablespoons. Hope you like it 🙂
This looks really good! I love how you made it dairy free. How lime-y did it end up tasting?
mmmmmmmmmm! Looks Yummy!
